Nick Cannon has laughed off rumours in the press that his marriage to Mariah Carey is on the rocks, insisting they couldn't be any happier.

The couple wed in the Bahamas in April 2008 after a whirlwind romance, but earlier this week gossip on websites were speculating their relationship was in trouble.

Reports alleged that Cannon was tiring of the Mimi's demands, with one source telling OK! magazine, "He's basically around to attend to her diva-ish ways.

But Cannon has dismissed the claims. He tells People.com, "Marriage is amazing. It's the best thing that ever happened to me."
